Initial analysis

The three-unit residential building at 1704-1708 20th Street in Potrero Hill, owned by Necesse LLC, has undergone significant renovations and improvements since its construction in 1966. The property has seen substantial bathroom and kitchen updates across all three units, with the most recent work completed in 2023 including vanity and lighting replacements, kitchen updates, and electrical improvements. Major renovations occurred in 2019 when all three units received bathroom and kitchen remodels, with associated plumbing and electrical upgrades. The building has maintained good general upkeep, with earlier maintenance work including reroofing in 2007 and deck repairs in 2002. In 2002, multiple building violations were issued regarding security, fire safety, and deck conditions, though all were promptly abated by June 2002.

Recent maintenance records show regular upkeep, including fixture replacements in 2023 due to damage and compliance with current codes. The building's infrastructure has been regularly updated, with significant electrical work completed in 2023 to improve safety and functionality. The property has experienced minimal recent complaints or violations, with only one building complaint in 2019 regarding unpermitted work, which was subsequently marked as not active. Outside the building itself, there have been a few neighborhood issues documented through 311 calls, primarily related to parking and tree maintenance, but these are not directly related to the building's condition or management. The consistent pattern of renovations and improvements, particularly the recent focus on electrical and plumbing upgrades, suggests active management of the property's maintenance needs.

Risk rating

How 1704-1708 20Th St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
